One Family … 30 Pet Snakes Puppies, kittens, bunny rabbits — furry, four-legged animals tend to be the most popular choice for families looking to purchase a pet. But 9-year-old Krista and her father, Jamie, prefer snakes.

Over the years, Jamie, a reptile enthusiast, has acquired 30 non-venomous snakes — including sizeable species, such as anacondas and pythons. At an early age, Krista developed a fascination with the slithering serpents, and she’s become fearless when handling, training and feeding them. The father-daughter duo has amassed a substantial fan base online for their educational videos about the often misunderstood creatures.

Health officials are investigating an outbreak of a rare skin infection in New York City’s Chinatown, affecting those who handle live or raw fish and seafood. The illness cannot be contracted through eating raw fish, and it is not contagious. The bacteria which causes the infection, Mycobacterium marinum, enters the body through cuts or abrasions — typically on the fingers — and produces redness, lumps and swelling under the skin of the hands and forearms. Thirty confirmed cases have been reported so far.

Dermatologist Dr. Melanie Palm explains how the infection is diagnosed and treated. “Usually, patients will come in, and they’ve had this several weeks, sometimes months, and so tissue is the issue,” she says. “You always want to get a sample of skin. A simple swab isn’t going to be able to yield the results from this. [The bacteria is] slow-growing, and it likes to grow at colder temperatures. That’s why it kind of likes digits — it likes hands and feet. It takes several weeks for us to get the results back. We start patients on antibiotics, but typically, almost the gold standard these days is doing dual therapy. So, actually starting two antibiotics, because you are susceptible to resistance.”

The Power of Hormone Replacement TherapyFrom severe breakouts to excessive hair loss, a hormonal imbalance can wreak havoc on your appearance.

Such was the case for Sonya, 35, who suddenly developed cystic acne, and began losing hair by the handfuls in the winter of 2012. Sonya was prescribed various medications to clear up her complexion and restore her thinning hair, but every treatment she tried was ineffective.

In early 2013, Sonya met with family physician and hormone specialist Dr. Melinda Silva, who discovered that Sonya’s hormone levels were significantly out of balance. Based on her lab results, symptoms and medical history, Dr. Silva came up with a personalized treatment plan for Sonya.
